i izeese LIQUID-LEVEL INDICATOR,

Application led December 1, 1924. Ygeral No. 753,065.

This invention relates to improvements in liquid level indicators as described in the present specification and illustrated in the accompanying drawings which form part of the same.

The invention consists essentially of the novel features pointed out broadly and specifically in the claims for novelty followving a description containing an explana tion in detail of an acceptable form o-f the invention.

The objects of the invention are to give more comfort to the driver of a motor car and to overcome the necessity of removing the cushion and lifting the seat in certain types of cars; and generally to insure economical and effective results.

In the drawings, Figure 1 is a perspective view of the sea-t broken away to disclose the tank and the tank iller and contiguous parts.

Figure 2 is an enlarged perspective View of the invention looking at the under side.

Figure 3 is a side view of the preferred form of the invention.

Figure 4 is a view of the spring-held cover for the tubes.

Fi ure 5 is a plan view of the cover showing the tubes in dotted lines.

Like numerals of reference indicate various parts in the different figures.

Referring to the drawings, the tank filler 1 has the cap 2 pivoted at 3 by the bolt 4, which continues on downwardly between the bands 5 which are held in position around the tubes 6 and 7 by the screws 8 and 9 and the bolt 4 at the other end is encircled by the spring 10 and the nut 11 forms the adjustment for same. Spring 1() holds thev cover 2 in place over the open ends ofthe tubes 6 and 7 thus avoiding any dust entering or any rattle from same while the car is in motion. The tubes con tinue on downwardly at 12 and 13 and are bent inwardly at 14 and 15- having the union joints 16 and 17 midway of their length, the straight parts 18 and 1.9 are rigidly secured to the spout 20 which 1s reduced at 21 to suit the curve of the tank 22 and this reduced portion 21 is open at 23 and has the flanged part 24 projecting therefrom to form an abutment for the arm 25 which is secured by the bolt 26 passing through the opening 23 and is rigidly secured to the top by the nut 27.

The arm 25 carries the U-shaped bearing bracket 28 which is pierced midway oflits length on the two legs of the U to receive the bolt 26 and on one leg of the U the bridge piece 39 having the legs 40 and 41 to span the opening 42 is rigidly secured. The closed end of the U is turned up and pierced at 43, 44, 45 and 46 to form the sliding member for the loop 47 which has the rigid piece 48 at the centre to operate with the forked end 49 of the indicator arm 50 which registers on the dial 51 as the iioat rises andrfalls. The loop 47 forms the sliding member and is operated by the arm 53 which is pivoted at 54 and at the other end 55 is Vpivoted to the short leg 56 of the U-shaped arm 57. of the U-shaped arm 57 is pivoted at 58 through the hole 59 of the arm 25 and the long leg of the U-shaped arm carries the float 60 at the extreme end.

In the operation of the invention, the float mechanism, which includes the .arm

portion, is first placed inside the tank and then securely fastened to the receptacle, so that when the tank" is being filled the float of the spout 2()V L T21" -F1C E? The closed end will rise therein and indicate the quantity of gasoline that is inside through the in-I dicator attached in a suitable place. This device is fo-r certain well-known types of cars which have their tanks located underneath the drivers seat and thus eliminates the necessityfof the passengers moving from theirseats and vat the same time Vindicate the quantity of gasoline in reserve.

The device may, of course, be changed to meet with the requirements of the different tank constructions without in anyway departing from the main features as herein shown. and described.

What I claim is:

liquid level indicatorl comprising an arm having guide brackets on one face thereof, a bracket adapted for fastening said arm to a receptacle, a rod pivotally mounted in one end of said arm and having a crank endadjacent to said arm, a fioat secured fto lthe outermost end of said rod, a loop slidably mounted in said guide brackets anda link Connecting one end of said loop to the crank end of said rod, said loop having a cross member intermediate its ends, a spindle pvotaillyi" mounted at;Y one end' at a point adjacent to said loop and having a fork-shaped portion'at right angles thereto engagingsaid cross member of said loop, Y0 an indicator secured at the other end of said Y spindle, and a dial secured adjacent'to said indicator. l

In testimony whereof I have aixe'd my signature this 28th day of November, 1924 l5 at thel city o-f Toronto.
